The lifespan of a bird's nest depends on the species. The building process can take from two days to three weeks. Once built, the nesting period for baby birds can last from two to ten weeks before they leave the nest. While most young birds are ready in two to six weeks, some predatory species may need up to two and a half months. Some species nest four to five times per year, so a nest could remain in use for several months. For specific information about a particular nest's longevity, it is best to consult a wildlife professional.

Tree removal can be quite expensive, especially for larger projects, but you can use the following tips to help keep costs down:

• Do the yard cleanup afterward yourself

• Choose to leave the logs on your property and split them yourself

• Opt to leave the stump in the ground and tackle stump grinding yourself

• Pull permits for tree removal, if necessary, to avoid fines

• Pay to have multiple trees removed at once

• Remove tree in the late winter or early spring during off-season

It depends on the type of tree. Typically, late spring on the cusp of winter is ideal for trees about to emerge from dormancy and produce new buds. That said, late fall is ideal for certain deciduous trees prone to bleeding sap. Avoid trimming trees in early spring, when they’re prone to disease.

In some states and municipalities, you will need a permit to remove a tree on your property. In many cases where permits are required, a tree must reach a maximum height before a permit is required to remove it. You can either ask your local building department or a tree removal professional if you’ll need a permit. If you do, you can expect to pay between $50 and $150 for the permit alone. Your tree removal company should pull the permit for you and include the permit fee in your total.
